Private Disk
Private Disk is a disk encryption application for the Microsoft Windows operating system, developed by Dekart SRL. It works by creating a virtual drive, the contents of which is encrypted on-the-fly; other software can use the drive as if it were a usual one. One of Private Disk's key selling points is in its ease of use, which is achieved by hiding complexity from the end user (e.g. data wiping is applied transparently when an encrypted image is deleted.) This simplicity does however reduce its flexibility in some respects (e.g. it only allows the use of AES-256 encryption.) Although Private Disk uses a NIST certified implementation of the AES and SHA-256/384/512 algorithms, this certification is restricted to a single component of Private Disk; the encryption/hash library used and not to Private Disk as a complete system.
